// The fact that he came from a devolved UK country that wanted nothing to do with the great NHS, would have made him a FOREIGNER. //
There is only one NHS in the UK. The welsh and the scottish have been given the power to spend the NHS budget in their areas, it does not mean it is a separate or different NHS, it is all part of the same thing, as will be the Manchester region who have been given the budget from central Government.
Scotland, Wales, Manchester do not have their own tax raising powers for health. If they were funding their hospitals locally then they could charge the customer/patient who was not local, but they aren't.
